INSTRUCTIONS
Vent or tube flushing hole pattern:
2.5” internal diameter.
Start one set 6” from end or top of sensor
holes. Drill two holes at 0° and 180°.
Start second set of two holes at 12” from
sensor holes, drill at 90° and 270°.
Sensor area hole pattern:
1.0” internal diameter, 1.5” on center from
1.0” above stop pin.
NOTES
• Clean and degrease pipe prior to
modifications
• In marine and other fouling sites paint
inside and out with anti-fouling paint
• Clean pipe at least twice a year

NOTES
• PVC pipe must be firmly secured to its base or mount to prevent loss in high flows
• Mount and pipe should be treated with anti-fouling paint if in fouling environment
• Secure submerged parts to shore with chain or SS wire rope to a fixed object
• Never clamp sonde directly to mount

INSTRUCTIONS
Vent or tube flushing hole pattern:
2.5” internal diameter.
Drill one set of two, starting 6” from sensor
holes at 0° and 180°. Drill second set of two
12” holes upwards at 90° and 270°.
Sensor area hole pattern:
